Aug 10 (Reuters) - A California jury on Friday found Monsanto liable in a lawsuit filed by a man who alleged the company’s glyphosate-based weed-killers, including Roundup, caused him cancer, and ordered the company to pay $289 million in compensatory damages.

The case of school groundskeeper Dewayne Johnson was the first lawsuit alleging glyphosate causes cancer to go to trial. Monsanto, a unit of Bayer AG following a $62.5 billion acquisition by the German conglomerate, faces more than 5,000 similar lawsuits across the United States.
